Dr. Wernher Magnus Maximilian Freiherr von Braun (23 March 1912–16 June 1977)[1] was a Germanengineer and scientist. He worked as a rocketdesigner between the 1930s and 1970s.[2] Some people say he was the most important rocket engineer of the 20th century.[3] He worked for the Nazis during World War II. After World War II, he went to the United States. There, he worked for NASA. In 1955, ten years after entering the country, von Braun became a US citizen.

In 1920, he moved to Berlin. During the first school years, von Braun attended a Frenchsecondary school in Berlin.[5] At the age of 13, he got a telescope. This gift raised his interest in astronomy.[5] Because of bad marks, von Braun had to attend a boarding school near Weimar, in 1925. He bought with his extra money the book Die Rakete zu den Planetenräumen (English: The Rocket Into Interplanetary Space) by Hermann Oberth, which is the basis of the modern rocket research.[5] In 1928, he attended the boarding school called Hermann-Lietz-Internat on the German island Spiekeroog. In 1930, he passed his final exams.

After the Nazis came to power, he joined the S.S..[1] On 27 July 1934, von Braun received a Ph.D. from the Technical University of Berlin.[2] "Max" and "Moritz", two rockets developed by him, went as high as 2,200 metres (7,218 ft) in December 1934.[7] The tests were made in a small village in Kummersdorf, Germany. In 1936, von Braun and his team developed the next generation of rockets, the A-3.[8] The test area in Kummersdorf was too small for this newly-developed rocket. Together with his team of about 90 people, he had to move to a bigger test area in Peenemünde.[5]

Von Braun worked in Peenemünde between 1937 and 1945. There, he started to develop a new rocket called A4 (Aggregat 4). After some tests, the rocket was renamed to V-2.[9] The "V" is for the German word "Vergeltung", which means revenge. This was the first long range ballistic missile to be used in war.[10] It was able to carry a one ton warhead up to 50 miles into the air, and travel hundreds of miles to a target.[10] In 1943, Germany started a mass production of this rocket using thousands of concentration camp prisoners as factory workers.[11] They fired thousands of these rockets at targets in Antwerp and Great Britain, especially London.[11] More than 1700 V-2 rockets landed on Antwerp, killing more than 3,700 people.[12] Von Braun and his team started to develop the new generations of these rockets, the V-9 and V-10, which were for targets in the US.[1]

Von Braun and about 100 other scientists were brought to America in 1945 after they surrendered.[13] They began to work for the United States Army at Fort Bliss, Texas, where they instructed American soldiers in launching captured V-2s. He became an American citizen in 1955. During the 1950s, von Braun tried to get support for an American space program. When the Soviet Union launched Sputnik, the United States finally started a space program. At first, the Navy was in charge, but their first Vanguard satellite was destroyed when the rocket blew up on the launch pad in December 1957.[14] The satellite program was given to the army, and the more experienced von Braun was able to start work with the rest of his team.[13] The Redstone rocket put a satellite into orbit on January 31, 1958.[14]

In 1950 Von Braun started work at the Army's new Redstone Arsenal in Huntsville, Alabama, which later became NASA's Marshall Space Flight Center.[13] There, he and his team developed the Redstone missile, similar to the V-2. In 1959, Von Braun and other Germans were transferred to NASA along with all Army space activities. His final and most successful rocket was the Saturn V, which carried astronauts to the moon. However, after the Apollo 11 Moon landing in 1969, public support for the space program declined. In 1972, von Braun retired from NASA and went to work with Fairchild Industries, in Maryland.[13]

Von Braun's work was able to give humankind a wider view into the universe. His rockets helped people reach the moon and send out spacecraft like Voyager 1. NASA is using his ideas to make the Ares V rockets.[16]
